FIGURE 23-2:

Note:
Select the desired HLVD trip point by writing the
value to the HLVDL<3:0> bits.
Set the VDIRMAG bit to detect high voltage
(VDIRMAG = 1) or low voltage (VDIRMAG = 0).
Enable the HLVD module by setting the
HLVDEN bit.
Clear the HLVD interrupt flag (PIR2<2>), which
may have been set from a previous interrupt.
If interrupts are desired, enable the HLVD
interrupt by setting the HLVDIE and GIE/GIEH
bits (PIE2<2> and INTCON<7>, respectively).
An interrupt will not be generated until the
IRVST bit is set.

When the module is enabled, the HLVD comparator
and voltage divider are enabled and consume static
current. The total current consumption, when enabled,
is specified in Section 27.0 “Electrical Characteris-
tics”. Depending on the application, the HLVD module
does not need to operate constantly. To reduce current
requirements, the HLVD circuitry may only need to be
enabled for short periods where the voltage is checked.
After such a check, the module could be disabled.
23.4
The internal reference voltage of the HLVD module,
specified
Characteristics”, may be used by other internal
circuitry, such as the programmable Brown-out Reset.
If the HLVD or other circuits using the voltage reference
are disabled to lower the device’s current consumption,
the reference voltage circuit will require time to become
stable before a low or high-voltage condition can be
reliably detected. This start-up time, T
interval that is independent of device clock speed.
The HLVD interrupt flag is not enabled until T
expired and a stable reference voltage is reached. For
this reason, brief excursions beyond the set point may
not be detected during this interval (see
Figure
PIC18(L)F2X/4XK22
23-3).
